I’ve overseen the installation of two Mitsubishi 9900-series UPS systems. In the US, Mitsubishi Electric Power Products, Inc (MEPPI) sells the systems. I believe that in other parts of the world, Toshiba sells the same UPS systems as the G9000-series through their TMEIC joint venture with Mitsubishi. We use the optional external “NetCom 2” SNMP modules to monitor the MEPPI UPS systems using our internal management systems. Finding the correct MIB to use proved to be a challenge!
